STILI..

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application led November 20, 1917. Serial No. 202,895.

To all whom t may concern:

y Be it known that I, ARIEL C. JEWELI., a citizen of the United States, residing at Chicago, in the county of `Cook and State of Illinois, have invented certain new andl for another kind ofheat. Heretofore it has been customary to construct the still special for each kind of heat, although the main bodies of the various stills are all vsubstantially similar. The invention has among its objects the production of an interchangeable still construction of the kind described that is simple, eiiicient, economical, convenient and satisfactory for use wherever found applicable. More particularly it relates to an improved still having a detachable bottom or container and associated heating means, whereby a portion of the still may be easily and quickly transferred to another bottom and a different source of heat employed. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my inventionconsists in the novel construction, arrangement and combination of parts herein shown and described and more `particularly pointed out the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

of the still with one of my improved inter changeable bottoms attached thereto, and adapted to be heated by gas or the like;

Fig. 2 is a sectional view of a similar bottom arranged for heating the contents of the bottom by steam or the like; and

Fig. 3 is a similar view showing'a bottom equipped with electric heating means.

Referring to the drawings, it maybe mentioned that I -have not shown a vcomplete still in all its details as this is immaterial in so far as the present invention is concerned. For the purposes of illustration, I have shown a portion of the still as illustrated in my pending application Serial No. 198,025,l filed October 23, 1917, in which 1 represents the still body shell or casing thereof provided withi a depending part 2. Referring particularly to Fig. 1, 3 represents a bottom portion having upturned side walls 4,4 forming a pan-shaped receptacle of the desired size and of a contour to closely fit the contour of and frictionally engage the part 2 of the still. I have shown the upper edge or rim of the wall 4: turned overas at 5, adding strength and rigidity as well as obviating the sharp edge. In addition this facilitates assembling the top and bottom and improves the appearance. In

the construction shown I have shown the4 upper body part 1 grooved or corrugated as at 6, and a flange or ring 7 secured thereto, which may seat on the top edge or rim of the bottom part. tween the ring 7 and the turned over portion 5 I have illustrated packing 8 of the desired material. While I have found the packing is` not essential, it is nevertheless desirable and in most cases I prefer to employ the same. illustrated in the above figure, 9 represents a suitable gas heater or burner carried by a base having a support l0 for the still, and provided with legs 1'1.l Any equivalent construction may be employed.

In Fig. 2 I have illustrated asimilar receptacle 4, but provided with a steam coil 12, having the intake and discharge pipes 14 and 13. It will be noted that with` the exception of the change in method of heat- Within the space be' In the type of apparatus ing the contents of the base the parts 3,

I electric coils or heaters 15 are shown asso- Flgure 1 1s a sectional view of a portion ciated with the bottom part. l It is immaterialjust how the coil 12 or the electric heaters 15 or the gas heater 9 be assembled or associated.

It" will be noted by referring to Fig. A

1 that the depending endv 2 of the upper part of the stillextends substantially close to the bottom 3 of the receptacle. it is only necessary to extend the same be- While.

low the lowest level of the water within the and if any, its escape is prevented by the packing 8. The advantages of the construction are many. Among them it may be mentioned that a small stock of completed stills may be carried as the particular type ordered may be assembled in a moments time. A user may have a still and several diferent bases or bottoms so that he can use the desired heat, for example steam from his heating system in the winter and gas or electricity in the summer, or at such time as the steam cannot be obtained., The bottoms may be interchanged without tools or skilled labor, and immediately at such time or times as may be desired.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of 'parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is vl. A still comprising'a body part and a detachable pan-shaped bottom part therefor, said parts of a contour and size to frictionally engage each other, and means for supporting the body on said bottom part with the lower edge of the bodyadjacent the bottom thereof to form a water seal and heating means associated with the bottom part.

2. In a device of the kind described, a pan-shaped bottom` having its upper edge reame@ rolled outward and reinforced, and means for heating the pan, in combination with a body part provided With depending edges adapted to be inserted inside the pan and snugly fitting the same and extending to substantially the bottom thereof to form a water seal, a circumferential groove in the body, a ring within the circumferential groove adapted to rest in close proximity to the top of the pan, and packing material between the ring and to of the pan.

3. In 'a still, a main ody part comprising the still proper, in combination with a cooperating detachable .bottom therefor provided with means for heating a liquid therein, and means for forming a water 'seal between the body and the bottom.

4f. In a device of the kind described, a still body provided with a depending marginal flange, in combination with a coperating detac able bottom for said body provided with upwardly extending walls, whereby the depending walls of the body will extend therein below the water level to form a water sealv between the two, and means for packing the juncture of the upper part of the bottom with the wall o f the body to render the same vapor tight.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

ARIEL C. JEWELL.
